69 STUDIES ON THE FAUNA OF CURAÇAO AND OTHER CARIBBEAN ISLANDS: No. 198 Additional notes on Caribbean tiger-beetles of the genera Cicindela and Megacephala by P. Wagenaar Hummelinck (Lab. Zool. Oecol. & Taxon., Utrecht) Another small collection oftiger-beetles which was made by the author notes during his visits to the Antilles may justify these additional to the papers of JONGE POERINK, on Cicindela (1953, this series vol. 4) and the present author, on Megacephala (1955, vol. 6).

Elytrae ofa female specimen ofCicindela from Aruba,showing position ofa number of small erect setae in which may be distinguished: a) a single row ofabout 15- of about the 30 near the lateral margin, b) a scattered longitudinalrow (in principle) 10 on dorsal scattered of small less the part, c) an irregularly group setae, more or bordering proximal part of the dark area. The author is indebted to Mrs. C. S. OLDENBURGER - EBBERS, Mrs. J. S. DE LEEUW VAN WEENEN - DE HART and Mr. F. VAN DER HEIDE for allowing him to include a number of measurements and other data, produced during their student’s practical course in taxonomy at the Zoo- logical Laboratory of the Utrecht University in 1967-1969. CARLA OLDENBURGER (cf. Table 2, Figs. 27-34) and JEANNETTE DE LEEUW VAN WEENEN (cf. Figs. 39-41) studiedthe greater part of the Cicindela material, while VAN DER HEIDE (cf. Table 5, Figs. 42-46) examined most of the Megacephala specimens. Loans from the Science Museum ofthe Institute of Jamaica and from the British Museum (Natural History) are gratefully acknowledged. Several interesting specimens collected by Dr. Ir. R. H. COBBEN (Wageningen) and Dr. F. CHALUMEAU (Guadeloupe) have also been studied, while a few specimens from the Zoölogisch Museum of Amsterdam and the Rijksmuseum van Natuurlijke Historie at Leiden are included for comparison. Dr. 71 CHALUMEAU and MICHAEL A. IVIE (Columbus, Ohio) kindly informed me about their activities. Furthermore I with Dr. THOMAS H. coleopterological greatlyenjoyed my contacts FARR (Kingston, Jamaica) and Mr. C. M. C. BROUERIUS VAN NIDEK (Voorburg, Netherlands). A few illustration from the two preceding reports have been reproduced again (Figs. 14 and 20, Pis. I—II and V-VI) to make these additional notes a little more attractive to all those who share the author's admiration for these most engaging elements of the Antillean beetle fauna. I am indebted to the official artist of the Zoological Laboratory of Utrecht Mr University, H. VAN KOOTEN for the excecution of the photographs. If not otherwise stated, all measurements have been taken from specimens preserved in alcohol. The length of the elytron - considered to be a suitable measure for comparing relative of - width of sizes body and legs has been measured from shoulder to apex. The an elytron has been taken as being the half ofthe width of the abdomen; when measured separately its maximum width should be about 20% (cJ}-25% (?) more (cf. Fig. 26, and Stud. 6 fig. 2). The is defined the of and it is body-length by adding up length elytron, pronotum head, though evident that a body-length without the protrudingparts of abdomen and labrum,will often be quite different from the body sizes as given in literature. Not much value be attached these which be taken ought to to measurements, hardly can in - be of for mutual an exact way they may, however, importance comparison. All new localities indicated by station numbers have been described in these Studies, vol. 63 (1981). The greater part of the material has been presented to the Zoologisch Museum of Amsterdam, while other specimens have been deposited at the Rijksmuseum van NatuurlijkeHistorie, Leiden, the British Museum (N.H.), London, The Institute of Jamaica, Kingston, and the Institut de Recherches Entomologiques de la Caraibe, Guadeloupe. It is to be regretted that in some cases the poor state ofpreservation reflects accidental collecting which undertaken with the of insects. duringtrips were not purpose collecting Although the author admires the taxonomical work ofRIVALIER (and other coleopterolo- gists), his nomenclature intentionallywas not used, as the present publication only aims at additional information in which his giving some to two previous papers certainly more satisfying classification was not used. The few data regardingthe penis should be considered only as a stimulus to give more attention to the structure ofthe male copulatory organ when studying the modest thoughinteresting cicindelid fauna of the Antilles.

See also Fig. 27. The labra ofthe Margarita specimens are uniform in having 6 submarginal setae; half of the Bonaire specimens possess the samenumber, while the others have 7-8 setae; oneAruba animal has 6 sdl je, the other four 7-9.
